We created a JCifsFileSystemView that allows to browse the Windows 
domain in a JFileChooser. The JFileChooser calls the FileSystemView in a 
background thread. That thread is interrupted during the showDialog() 
call of the JFileChooser. Depending on the timing this might interrupt 
the connect() call since enumeration of the initial directory already 
started.
